For a multimillion dollar manufacturing company in Ohio, we were able to have machinery and equipment reclassified to a non-taxable status as pollution control equipment. In the same audit period, we negotiated a depreciable life of 10 to 12 years on certain assets that the state had originally valued based on a depreciable life of 15 to 17 years. Bottom line: The result of these two actions was $150,000 in annual tax savings for the company.
